Slick slider text on top of images

Question

I'm trying to make a pretty normal carousel, with two arrows on either side in the vertical middle, and text with a button in the middle on top of the image. I cannot get anything to appear on top of the image though, even though the arrows and text are all absolute and have a higher z-index. Here's a codepen with my code. http://codepen.io/kathryncrawford/pen/AXmVAz

And here's my HTML

<div class="slick-slider">
    <div>
        <img class="img-fluid" src="http://www.placecage.com/1500/750" alt="">
        <div class="info">
        <h1 class="slider-heading">Heading</h1>
            <p class="slider-subheading lead">Subheading</p>
            <a class="btn btn-large btn-danger" href="">button text</a>
        <p class="down-arrow">
            <a class="btn btn-large btn-down-arrow" href="#theend">
                <i class="fa fa-chevron-down fa-lg" aria-hidden="true"></i>
            </a>
        </p>
        </div>
    </div>
    <div>
        <img class="img-fluid" src="http://www.placecage.com/1500/750" alt="">
    </div>
    <div>
        <img class="img-fluid" src="http://www.placecage.com/1500/750" alt="">
    </div>
</div>

My CSS (the slick css is not included here, but it is in the codepen)

  .slick-slider img { /* keep images full screen */
    width: 100%;
  }

  .chevron-container { /* full slider height container for chevrons */
    height: 100%;
    position: absolute;
    width: 100px;
  }

  .slick-right { /* keeps right arrow to the right */
    right: 0;
    top: 0;
  }

  .chevron-container > .fa { /* positions chevrons in vertical center */
    bottom: 0;
    color: white;
    font-size: 10em;
    height: 1em;
    margin: auto;
    position: absolute;
    top: 0;
    width: 5em;
    z-index: 10;
  }

  .slick-slider .info {
    color: white;
    position: absolute;
    width: 100%;
    height: 100%;
    top: 0;
    left: 0;
    line-height: 100vh;
    text-align: center;
    z-index: 10;
  }

  .slick-slider .info > div {
    display: inline-block !important;
    vertical-align: middle;
  }

And my JS

jQuery(function($){
  $('.slick-slider').slick({
    accessibility: true,
    adaptiveHeight: true,
    arrows: true,
    infinite: true,
    mobileFirst: true,
    nextArrow: '<div class="chevron-container slick-right"><i class="fa fa-chevron-right" aria-hidden="true"></i></span><span class="sr-only">Next</span></div>',
    prevArrow: '<div class="chevron-container"><i class="fa fa-chevron-left" aria-hidden="true"></i></span><span class="sr-only">Previous</span></div>',
    slidesToShow: 1
  });
});

Solution 1

You have to do

.slick-slide {
    /* ... */
    position: relative;
}

so that the .info stuff knows it should be absolutely positioned to it's parent.

Solution 2

Just add position: relative to .slide-slide.

jQuery(function($){
  $('.slick-slider').slick({
    accessibility: true,
    adaptiveHeight: true,
    arrows: true,
    infinite: true,
    mobileFirst: true,
    nextArrow: '<div class="chevron-container slick-right"><i class="fa fa-chevron-right" aria-hidden="true"></i></span><span class="sr-only">Next</span></div>',
    prevArrow: '<div class="chevron-container"><i class="fa fa-chevron-left" aria-hidden="true"></i></span><span class="sr-only">Previous</span></div>',
    slidesToShow: 1
  });
});

.slick-slider
{
  position: relative;

  display: block;
  box-sizing: border-box;

  -webkit-user-select: none;

You're correct, but .slick-slide (not slider) is not set to position:relative;, once you do that, it will be fixed.

@KathrynCrawford yes its added to .slick-slider but not added in .slick-slide.

[Kathryn Crawford]

Oh! Duh! It's always something simple isn't it. Thanks!
